Spreadsheet - It's impossible to change cell selection on a custom callback

created 9 years ago

Using the MVC spreadsheet control, I am trying to change the active cell selection during a custom callback action, but not having any luck.

I've tried doing it this way:
https://www.devexpress.com/Support/Center/Question/Details/T126769

But that doesn't have to seem any effect when I return to my view.

I've also tried this way, on the client side:
https://www.devexpress.com/Support/Center/Question/Details/T333741

It works, but it is extremely, unfeasibly slow to do it on the client side -- at least doing it this way.

I haven't come across any other ideas. Is this possible? If so, how? Thanks!

    Hello Nate,

    If you need to manage a document in the Controller, I recommend you use the approach described at Spreadsheet - How to access an active sheet in the Controller to get the document. Once you get it, use the solution from the ASPxSpreadsheet - How to change selection ticket to set a new selection range.

    I'm not sure about the client-side approach. Usually, client-side solution performance is higher as compared to the server-side one. Would you please demonstrate how you implemented that solution in your project?

        Unfortunately that is not working -- your suggestion was the same exact link that I told you didn't work.

        I attached a sample project which has a custom button on a custom tab that calls back into the controller and (tries to) change the selection. If you could please give me a working solution, I would appreciate it very much. Thanks!

          Hi Nate,

          Thanks for the clarification. The described behavior looks incorrect and I have forwarded it to our R&D team for further research.
          Please bear with us.

            Thanks Artem. I'll be looking forward to further information.

            It's actually a big deal. I've implemented functionality to move one or more columns to the left or right within the spreadsheet, but because I can't change the selection, the result is that the data gets moved, but the selection remains the same. This causes confusion for the user, and prevents the user from additional column move actions without re-selecting columns . What I need is to be able to move the selection along with the data.
